I used the code #*7337# to unlock my samsung J700 and it did unlock but has changed my imei number to 000000000000 is there a way to get my old number back or reset it??? ron


That's not an unlock code my friend, it just part of instruction set to unlock samsung phone. You must have samsung J700 network unlock code and you can get that from your network provider or buy from third party sites. But don't ever try free samsung unlock code since almost of them is just fake unlock code.

My samsung Duos gt-b5722 not showing any network. when i insert sim it shows full signal but when i dial a number it shows emergency call only. i cant send any message. when i call on my no. it says its...


Try other sim cards in the phone to be sure the problem is not from the sim. When you are sure the problem is not from the sim, try to reset the phones's factory settings. If it still does not work, then flash the phone.
If the fault was detected to be a sim fault, then get another line of the same network, and call your mobile service operators.
Hope this was helpful?

I want to unblock my samsung j700


Unblock or unlock?

It can be 'unblocked' if its barred but if its 'unlocked' you want then...

BACK UP YOUR FILES BEFORE UNLOCKING
This will also bring the phone to default settings
1. First do a CUSTOM reset: *2767*2878# (star 2767 star 2878 hash)
turn off the phone
2. take out the battery and sim and put wrong network SIM and insert a half of it,
so it won't ask for network password and shows "Insert SIM" message.
Now put the battery ,and switch the phone on .(phone shows "Insert SIM" message.)
3.With out turn off the phone push the sim fully in. At this stage the phone is still asking to "Insert SIM"
4. Make a FULL reset by typing: *2767*3855#(star 2767 star 3855 hash)
5. The phone should reboot working with "wrong" sim inside.
6. Make a Change the NCK password to 8 zeros by typing: *7465625*638*00000000*00000000#
(star 7465625 star 638 star 8zeros star 8zeros hash)
7. Now Disable network lock By typing: #7465625*638*00000000#
(hash 7465625 star 638 star 8zeros hash)
Phone is unlocked (check with *#7465625#)
If network lock is still on reply back

Emerency calls only!!


Hi
Sounds like you have no signal for the network your on.
Even though the phone shows signal bars, this is for a reception it has found for other networks around you. Networks allow emergency calls to be made by all mobiles regardless of network.

Has it ever worked with your sim? Does it work in other areas you travel? Does it work with another networks sim?

Another possibilty is if you have only just got the phone was it from new? If you have purchased it second hand there is a possibility that the mobiles imei is on a barring list for being reported lost or stolen? If you call your network they have a data base they can check for you. If it is listed as barred there is nothing you can do apart from take it back to where you got it from?
Hope that helps?
